Product Description:
NdFeB Magnet - Neodymium Rare Earth Magnets
The NdFeB Magnet, also known as Neodymium Rare Earth Magnet, is a type of strong magnetic material that is widely used in various industries. It is made using the sintering process, which involves compacting and heating a mixture of neodymium, iron, and boron powders. This process creates a powerful magnetic material with high energy density and excellent magnetic properties.
One of the key features of NdFeB Magnet is its coating, which provides protection against corrosion and improves its durability. It is available in three different types of coating - nickel, epoxy, and zinc. The nickel coating is the most commonly used and offers excellent resistance to oxidation and high temperatures. The epoxy coating provides a layer of insulation and protects the magnet from external elements. The zinc coating is suitable for applications that require a lower level of corrosion resistance.
With a maximum working temperature of 230ºC, NdFeB Magnet is suitable for use in high-temperature environments. Its strong magnetic properties remain stable even at elevated temperatures, making it an ideal choice for applications that require a reliable and powerful magnet.
Precise tolerance is another important attribute of NdFeB Magnet. It has a tolerance of +/- 0.05 mm, which means it can maintain its shape and dimensions with high accuracy. This makes it suitable for applications that require precise positioning and alignment, such as in motors, sensors, and medical devices.
In conclusion, NdFeB Magnet is a versatile and reliable magnetic material with a sintering process, nickel, epoxy, or zinc coating, high working temperature, and precise tolerance. Its superior magnetic properties make it an essential component in many industrial and consumer products, from electronics and automotive to healthcare and renewable energy. Choose NdFeB Magnet for your magnetic needs and experience its exceptional performance and durability.
